About this document
Meiosis Class Notes 1.20.15 by charley_zhao1 is a document available to read on EtoBox.
Meiosis reduces the number of chromosome sets from 2n to n through two cell divisions. During meiosis I, homologous chromosomes pair up and exchange DNA through crossing over. Sister chromatids remain attached as homologs separate and move to opposite poles. Meiosis II then separates sister chromatids without further DNA replication, resulting in four haploid daughter cells genetically distinct from the original diploid cell.
